Under the U.S. Army Corps of Engineers’ (USACE) Phoenix, Arizona and Vicinity (including New River) plan, the District and the USACE constructed the Arizona Canal Diversion Channel (ACDC). The 16.5 mile long ACDC provides 100-year flood protection to a 152 square mile watershed area in a highly urbanized area. The ACDC is an earthen trapezoidal channel from about 54th Avenue to Skunk Creek and a concrete lined channel upstream that is open for most of its length with covered sections near the Biltmore Resort and at the intersection of Central and Dunlap Avenues. The District and the USACE were partners in a cost share agreement for construction of the ACDC (IGA 77001, Public Law 91-611 also known as the 221 Agreement), while additional cost share agreements were in effect with the various cities for all recreational features.
Recreational features primarily include the Thunderbird Paseo Park in the City of Glendale, constructed along Reach 1 of the ACDC between 51st Avenue and 73rd Avenue.
Construction of the ACDC required numerous bridges to be built in the cities of Peoria, Glendale and Phoenix. Each city is responsible for the operation and maintenance of the bridges within their respective boundaries. Additionally, each city is responsible for maintaining any recreational and aesthetic features along the ACDC within its boundaries. The District is responsible for the operation and maintenance of the ACDC itself and its flood control features with the exception of a section of Reach 1 which is the responsibility of the City of Glendale.
